How to get rid of mineral buildup in slow cookers


Slow cookers are a convenient and easy way to prepare meals. However, over time, mineral buildup can occur in the appliance, causing it to function less efficiently. This buildup is often caused by hard water, or the minerals present in food. To get rid of mineral buildup in a slow cooker, there are several methods that can be used. One option is to fill the cooker with equal parts of white vinegar and water and let it sit for several hours before rinsing it out thoroughly. Another method involves using baking soda mixed with water to create a paste that can be spread on the affected areas and left for several hours before rinsing.

Regular cleaning and maintenance can help prevent mineral buildup from occurring in the first place. It’s important to follow the manufacturer’s instructions for cleaning your slow cooker since different models may have specific requirements or restrictions on what types of cleaners can be used. By taking care of your slow cooker properly, you’ll ensure that it continues to work well for years to come.

Overview of How to get rid of mineral buildup in slow cookers

Mineral buildup is a common issue in slow cookers due to the prolonged exposure of minerals from cooking water and ingredients. This can result in unsightly stains, and unpleasant odors, and even affect the taste of food. To get rid of mineral buildup, it is vital to clean your slow cooker regularly.

One method to remove mineral buildup is by using a mixture of equal parts water and white vinegar. Another effective way to eliminate mineral deposits is by using baking soda and warm water. This will help break down stubborn minerals that are hard to remove with just soap and water alone.

10 ways How to get rid of mineral buildup in slow cookers

1. Vinegar and Water Solution:

Unplug the slow cooker and let it cool down completely before cleaning. Next, mix equal parts of white vinegar and water in a bowl or container. Pour the mixture into the slow cooker until it covers all areas with mineral buildup. Let it sit for 30 minutes to an hour, depending on the severity of the buildup. Then, scrub off any remaining deposits using a soft sponge or cloth.

Rinse the slow cooker thoroughly with water and dry it completely before using it again. This method not only removes mineral buildup but also helps sanitize your slow cooker without harsh chemicals or abrasive materials that can damage its surface over time.

2. Baking Soda and Water Solution:

To prepare the solution, simply mix equal parts baking soda and water until you have a paste-like consistency. Then, apply the mixture to the areas with mineral buildup in your slow cooker. Let it sit for about 10-15 minutes before scrubbing with a soft-bristled brush or sponge. Rinse thoroughly with water once you’re finished.

3. Lemon Juice and Water Solution

To create the mixture, simply combine equal parts of lemon juice and water in a bowl. Next, pour the solution into the slow cooker and turn it on low heat for several hours. Allow the solution to soak into the mineral buildup before scrubbing it away with a non-abrasive sponge. For tougher stains, you may need to repeat this process or let it soak overnight.

4. Distilled Water Only

Distilled water is the best option to use in your slow cooker if you are looking to prevent mineral buildup. This type of water has gone through a process that removes all impurities, including minerals, making it more pure than tap or filtered water. Using distilled water will not only help prevent mineral buildup in your slow cooker but also ensure that your food is cooked with the cleanest possible liquid. In conclusion, distilled water is highly recommended for use in a slow cooker if you want to avoid mineral buildup. It is readily available at most grocery stores and is worth the investment if you want to extend the life of your appliance.

5. Citric Acid and Water Solution

To make a citric acid and water solution, simply mix one part citric acid with three parts water. To use the solution, pour it into your slow cooker and let it sit for several hours or overnight. Then empty the solution out and rinse the pot thoroughly with clean water. You may need to repeat the process several times if you have a lot of buildup.

6. Fabric Softener and Water Solution

Begin by unplugging the slow cooker and allowing it to cool down completely. Then, fill the inner pot with equal parts of warm water and fabric softener. Next, let the solution sit in the pot for several hours or overnight. The fabric softener will help to break down any mineral deposits that may have formed on the surface of the pot. After soaking, empty out the mixture and scrub away any remaining buildup with a non-abrasive sponge or brush. Rinse thoroughly with warm water and dry before using again.

7. Salt and Ice Soak

First, fill the pot with enough water to cover the affected area and add one cup of ice cubes. Then, sprinkle around half a cup of coarse salt over the ice cubes. Let this mixture sit for at least an hour or until most of the ice melts and dissolves into the water. Afterward, use a soft sponge or brush to scrub away any remaining minerals gently. You can repeat this process if there are still stubborn spots left behind.

8. Boiling Water and Dish Soap Soak

Fill the slow cooker with enough water to cover the mineral buildup. Turn on the heat and let it come to a boil for about 30 minutes. Next, add a few drops of dish soap to the water and mix it well. Let the mixture cool down for another 30 minutes before draining it out. Use a scrub brush or sponge to gently scrub away any remaining mineral buildup.

This method works because boiling water helps loosen up mineral deposits while the dish soap breaks down any remaining residue. It’s important to note that this method may not work for all types of minerals, so it’s best to consult your slow cooker manual or manufacturer for specific cleaning instructions.

9. Cream of Tartar and Water Paste

To make the paste, mix cream of tartar with enough water to form a thick paste. Apply the paste generously on the affected areas and let it sit for at least 30 minutes. Then, scrub the surface with a soft-bristled brush or sponge until all traces of mineral buildup are removed.

10. Commercial Slow Cooker Cleaner

To use a commercial slow cooker cleaner, simply follow the instructions on the packaging. Typically, you’ll need to mix the cleaner with water and let it sit in your slow cooker for a certain amount of time before rinsing it out thoroughly. Some cleaners may also require additional scrubbing or soaking for particularly stubborn mineral buildup.


Getting rid of mineral buildup in the slow cooker is not a difficult task. The most effective way to remove mineral deposits is by using white vinegar, baking soda, and water. These ingredients are readily available and affordable. However, prevention is always better than cure, so it’s essential to clean the slow cooker after every use and avoid using hard water for cooking. By following these simple tips, you can extend the lifespan of your slow cooker and ensure that your meals remain healthy and delicious. So go ahead and try these methods today.
